This petition was rejected

The Government e-Petitions Team gave the following reason:

We can't accept your petition because the UK Government and Parliament aren't responsible for the issue you raise. Children's crossings are the responsibility of your local council.

You could raise your issue with a local councillor, who represents you. You can use this page to find out who your local councillors are, and how to contact them:
